Paper Abstract

We discuss the need for evaluating the performance of a semiconductor laser in terms of the requirements imposed by the system in which it is used. We find that the median life-time for 45 Mb/s optical transmitters, based on the criteria of average power drift and extinction ratio degradation, is on the order of 104 h. This result is well below the demonstrated cw median lifetime of over 105 h for the (AlGa)As multimoded lasers used in the transmitter. The processes leading to the shortened transmitter lifetime are traced to laser degradation. Circuit strategies which compensate for the effects of the aging of the laser are presented.
